Just a quick question as I am currently writing up an SLA for a solicitor to look over on Tuesday, how many minutes downtime would be classed as 99.95%?

Regards,
Matty :)

take [(24hours/day) * (30days) * (60min/hour)] all * .0005 and you get 21.6 minutes

Many thanks, I was getting confused trying to work it all out lol.:blush:

Any time, even the veterans such as ourselves get confused.

You're a hosting veteran?

That's not nice Bob. ;)

2 years and running. Since veterans are usually in service for one year I would say I more than qualify.

PS props on the sale.

I was just wondering, and what constituted a "hosting veteran". I still felt like a n00b after 2+ years. :D

well we are always noobs but after awhile we tend to forget that.

I have been in hosting for 10 years, am I am still a nut, learn a lot after I discovered WHT. Wonderful forums

%100 - %99.95 = 0.05
not 0.0005 ! :D

yes, but 0.05% = 0.0005

Actually 0.05 % doesn't equal 0.005%, in that case you get 21.6 minutes, 99.95% uptime roughly would be about 1 1/2 hours for downtime, roughly.


Matt

No, 0.05% does mean you would multiply by 0.0005 because 0.05% of 1 is 0.0005

To prove it, do ([ 24 hours * 30 days * 60mins/hour ] / 100)*0.05 and you get 21.6 minutes again.

The 24 * 30 * 60 gives you the number of minutes in an average month, then when you divide by 100 you get one percent of the time, then you multiply by 0.05 to get 0.05% of the time.

Multiplying by 0.0005 is just a quick way of doing the / 100 * 0.05 step.

We need a math class. pixel_fenix was correct with his first response.

Edit: Then we can setup an English class for me.;)

Matt That is not correct, it would not be 1-1/2 hours of downtime.

60X24X365 then divided by 12 will give you the average minutes per month which is 43,800.

99.95% uptime would be 21.87 minutes of downtime.

Pixel_fenix was correct, I just averaged the minutes per month a bit differently.

Pixel_fenix was correct, I just averaged the minutes per month a bit differently. Thanks for confirming it. I knew this was going to be a confusing subject lol :D

my bad for skipping a step I tend to do that once in awhile in a simple math equation. Isn't this year a leap so theres an extra day or something.

If you want to get really picky then one way of working it out to cope with leap years is to use 365.25 instead of 365 days in a year. 365.25 is the average number of days in a year (as a leap year happens once every four years and 4 x 0.25 = 1) - although I'm sure nobody in the real world is going to fuss over that ;)

You would be surprised at how far some people will go. All just to get some cash back.

If you enter 99.95 in the Uptime Percentage box and hit Calculate, it will tell you the total downtime for the month. In this case, it's 21 minutes 36 seconds (based on this month).
